Abstract

Penurunan jumlah penumpang angkutan kota (koasi) di Kota Bekasi selama pandemi Covid 19 awal bulan Maret 2020 sangat dirasakan oleh pengemudi angkutan kota, penurunan tersebut terjadi bukan saja disebabkan oleh pandemi tetapi juga disebabkan oleh maraknya angkutan umum online (ojek online). Penelitian ini akan mengevaluasi besarnya pendapatan/upah pengemudi angkutan kota (Koasi) terhadap jumlah penumpang, biaya operasional per hari, dan karakteristik penumpang terhadap tingkatan kelayakan kendaraan selama pandemi dengan metode PCI dan analisis karakteristik penumpang dengan metode IPA. Berdasarkan hasil analisis maka diperoleh total biaya operasional selama pandemi untuk angkutan kota K02, K25 dan K11 dengan panjang rata-rata pegamatan sepanjang ±2,9 km adalah sebesar Rp. 656.649,00 per kilometer. Dengan rincian biaya BBM sebesar Rp. 19.890/km, biaya oli sebesar Rp. 77.318,00/km selama 6 bulan, biaya/upah Supir Rp. 540.000/km dan biaya overhead sebesar Rp. 19.442,00/km. Jumlah pendapatan supir selama 2 (dua) minggu untuk Koasi K25 sebesar Rp. 152.000,00, K11 sebesar Rp. 112.000,00 dan K02 sebesar Rp. 92.000,00. Tingkat kesesuian kelayakan kinerja pelayanan angkutan kota sebesar 95,6%. Tingkat kelayakan fasilitas dan pelayanan bernilai A, B dan C atau tingkat keamanan dan kenyamanan kurang dengan nilai GAP keamanan 0,28, kenyaman 0,58 dan kebersihan dengan nilai terendah yaitu 0,2.

Abstract

The Pantura Highway which connects Bekasi City and Bekasi Regency is the main acces for community mobilization, so it is necessary to optimize services and public transport needs to fulfill the Bekasi- Cikarang route of ±15,1 km. Analysis of the optimal number of fleets is carried out using the Break Event Point (BEP) method by taking into account the value of load factor, BOK, daily income and number of existing fleets based on data from field interview surveys. The research results show that the number of public transportation operating in 80 units out of 112 units. Operation time 5 hours/day with operational cost of Rp. 447.700,91/day. The load factor value is 61,7% and the average speed is 16,6 km/hour. The Bok value  for the PCI method is Rp. 4.323.695,75 per 1000 km or Rp. 652.878,-/day. The BEP value for the optimal number of fleets with the existing in currently 62 unit and for the future in 2027 it is 60 units. The optimal fleet number using the PCI BOK method is currently 43 unit and 42 unit for 2027.

Abstract

Pabrik PT. Hitachi Construction Machinery Indonesia telah mengalami banjir hampir setiap tahun. Banjir yang terjadi pabrik PT. Hitachi Construction Machinery Indonesia disebabkan karena area pabrik memiliki elevasi yang lebih rendah dibandingkan area sekitar. Menyadari bahwa lahan resapan di sekitar area pabrik semakin berkurang sehingga kemungkinan jumlah debit banjir bertambah semakin membahayakan area pabrik maka perlu dilakukan analisa kapasitas daya tampung sistem drainase yang ada dengan perkiraan debit banjir rencana. Dilakukan perhitungan kapasitas dari sistem drainase existing dan kapasitas dari sistem drainase yang baru. Data curah hujan yang digunakan adalah data curah hujan maksimum tahunan. Metode analisis curah hujan menggunakan metode gumbel. Perhitungan debit rencana menggunakan metode rasional. Kemudian dilakukan perhitungan kapasitas saluran drainase existing dan redesign untuk saluran-saluran juga kolam yang kapasitasnya tidak memenuhi. Kapasitas sistem drainase sesuai dengan debit rencana. Sesuai hasil penelitian debit existing sebesar 1,185 m³/s mampu menampung hingga debit rencana periode ulang 100 tahun sebesar 0,54 m³/s. Beberapa saluran sekunder harus dimodifikasi dimensinya agar tidak terjadi genangan di area yang memiliki elevasi yang rendah yaitu pada ditch 14, ditch 15 dan ditch 34. Kolam retensi existing tidak dapat menampung debit banjir maka perlu dibuatkan kolam retensi yang baru. Pada periode ulang 100 tahun volume yang tidak tertampung sebesar 45.148,27 m³ dan membutuhkan ground water tank dengan luas permukaan 10.085,93 m² dengan tinggi 4,48 m.

Abstract

Cikarang Bekasi Laut (CBL) is a fixed-dam river-flow that flows through the building for upstream srengseng channel. Srengseng Hilir Secondary-Channel has 32 buildings for watering the rice fields in the Sukatani sub-district. The problem happened in the distribution of water when there is a loss of irrigation water due to infiltration of water into the soil where the soil is saturated. This causes a shortage of debit for field irrigation due to water loss in the secondary channel. The method used in Water Supply Evaluation of Irrigation Cikarang Bekasi Laut (CBL) for the Secondary Channel Srengseng Hilir D.I. Jatiluhur are the maximum discharge data, minimum discharge, and average discharge of the Fixed Cikarang Bekasi Laut (CBL) Dam in 5 year-period and calculating water requirements and water availability in D.I. Jatiluhur. Result showed that the P1 channel has an irrigation area of 105 ha and a channel length of 1906 m with an actual discharge of 2714 liters/sec and has irrigation efficiency of 5.71%. Channel P2 has an irrigation area of 106 ha and channel length of 1006 m with actual discharge of 1560 liters/sec and has irrigation efficiency of 6.11%. P3 channel has an irrigation area of 137 ha and 894 m channel length with an actual discharge of 175 liters/second and has irrigation efficiency of8.41%. Channel P4 has an irrigation area of 50 ha and a channel length of 951 m with an actualdischarge of 180 liters/second and has irrigation efficiency of 21.10%. Channel P5 has an irrigationarea of 71 ha and a channel length of 835 m with an actual discharge of 274 litters/sec and has irrigationefficiency of 37.97%. Channel P6 has an irrigation area of 74 ha and a channel length of 775 m with anactual discharge of 411 liters/sec and has irrigation efficiency of 63.79%.

Abstract

Nowadays, delays in project often occur and cause various losses both for service providers and users. For the contractors, delays create the project cost overruns due to project overtime and can decrease contractor credibility in the future. This study aims to analyze a project delay by minimizing the work delays earlier. The analysis of a hotel building planning regarding the cost and time delays is done qualitatively by distributing questionnaires to the contractors and processing the responses using the SPSS software. The results of the S curve analysis and 30 factors that caused the project delay were identified and indicated that there was a delay value of 1.26% with five variables that most contributed to the delay in the construction project at PT. Wijaya Kusuma Contractors, i.e. reworking due to construction errors, low coordination between contractors and stakeholders, late material delivery, and equipment shortages.
